Implementation Reference

• src/index.ts:236-254 (handler)

  The execution handler for the 'write_note' tool. Extracts title and content from input arguments, validates presence, assigns a new sequential ID, stores the note in the in-memory 'notes' dictionary, and returns a textual success response.

  case 'write_note': {
    const title = String(request.params.arguments?.title)
    const content = String(request.params.arguments?.content)
    if (!title || !content) {
      throw new Error('Title and content are required')
    }
  
    const id = String(Object.keys(notes).length + 1)
    notes[id] = { title, content }
  
    return {
      content: [
        {
          type: 'text',
          text: `Wrote note ${id}: ${title}`,
        },
      ],
    }
  }

• src/index.ts:124-137 (schema)

  Input schema for the 'write_note' tool defining the expected object structure with required 'title' and 'content' string properties.

  inputSchema: {
    type: 'object',
    properties: {
      title: {
        type: 'string',
        description: 'Title of the note',
      },
      content: {
        type: 'string',
        description: 'Text content of the note',
      },
    },
    required: ['title', 'content'],
  },

• src/index.ts:121-138 (registration)

  The tool registration entry in the list of available tools returned by ListToolsRequestHandler, specifying name, description, and input schema for 'write_note'.

  {
    name: 'write_note',
    description: 'Write a new note',
    inputSchema: {
      type: 'object',
      properties: {
        title: {
          type: 'string',
          description: 'Title of the note',
        },
        content: {
          type: 'string',
          description: 'Text content of the note',
        },
      },
      required: ['title', 'content'],
    },
  },
